Beckham Jr. asked Bolt if they can train together

While NFL defenses won't ever have to worry about Usain Bolt's speed, Odell Beckham Jr., offered an even more frightening proposition.

He wants to train with the nine-time Olympic gold medalist - as if Beckham wasn't fast enough already.

Beckham asked Bolt about coordinating an offseason speed-training program after the NFL tweeted his 21.85 mph touchdown run against the Cowboys.

At the 2009 World Championship in Berlin, Bolt was clocked at 27.8 mph. Beckham has a ways to go to match that footspeed, but he was also wearing pads.

NFL defenses everywhere are probably rooting against that offseason training partnership.
